Monitored anesthesia care or IV sedation. For some procedures, you may receive medication that makes you sleepy and keeps you from feeling pain. There are different levels of — some patients are drowsy, but they are awake and can talk; others fall asleep and don’t remember the procedure. Potential side effects of sedation, although there are fewer than with general anesthesia, include headache, nausea and drowsiness. These side effects usually go away quickly. Because levels of sedation vary, it’s important to be monitored during surgery to make sure you don’t experience complications.
With regional anesthesia, your anesthesiologist injects medication near a cluster of nerves to numb only the area of your body that requires surgery. You may remain awake or you may be given a sedative. Spinal and epidural blocks involve interrupting sensation from the legs or abdomen by injecting local anesthetic medication in or near the spinal canal. Other blocks can be performed for surgery on your extremities, or limbs, blocking sensations from the arm or leg.

As with any other medical procedure, each type of regional/local block carries with it its own risks and benefits, which should be carefully considered and discussed with your anesthesiologist each time an anesthetic plan is chosen for a particular procedure.
For the epidural block, a special needle is placed in the epidural space just outside the spinal sac. A tiny flexible tube called an epidural catheter is inserted through this needle. Occasionally, the catheter will touch a nerve, causing a brief tingling sensation down one leg. Once the catheter is positioned properly, the needle is removed and the catheter is taped in place. Additional medications are given as needed through the epidural catheter without another needle being inserted. The medication bathes the nerves and blocks out the pain. This produces epidural anesthesia and analgesia.

For spinal anesthesia, the anesthesiologist advances the needle until he or she is able to inject some local anesthesia into the spinal fluid. Since a spinal block typically involves a one-time injection, the duration of your spinal anesthesia will depend on the type and amount of local anesthetic medication administered by your anesthesiologist.
Prior to performing a spinal or epidural block, your anesthesiologist may place monitors to watch your vitals signs. You will be placed either on your side with your knees and chin pulled as close to your chest as possible or sit with your arms and head resting on a small table. At this time, your anesthesiologist may choose to inject a small amount of relaxing medicine into your intravenous line if you require sedation. The anesthesiologist will feel your back, clean your skin with an antiseptic (bacteria-killing) solution, and place a sterile drape around the area. Your anesthesiologist may first inject some local anesthesia into the skin and then into the deeper tissues of the lower back - this may cause a slight burning or pressure sensation. Your anesthesiologist will then carefully insert the needle and advance it into the space between your vertebrae (backbones). Occasionally, you may feel a brief tingling sensation (paresthesia) during the procedure.

Emboldened, he spoke to Jackson, whopooh-poohed the idea, but nevertheless proposed to the nearby medicalschool that this substance could be a possible anesthetic.

Spinal and epidural blocks are forms of anesthesia that temporarily interrupt sensation from the trunk (chest and abdomen) and legs by injection of local anesthetic medication in the vertebral canal, which contains the spinal cord and spinal nerves. The spinal cord and spinal nerves are contained within a fluid-filled sac. The fluid-filled sac is called the dural sac and the fluid is known as cerebrospinal or spinal fluid

After surgery, you will be taken to the recovery room and monitored closely by recovery room nurse until your spinal or epidural block wears off. Typically, a spinal block lasts 2-6 hours depending the type and amount of local anesthetic given by the anesthesiologist. If you received an epidural catheter, it can be left in place for several days after surgery to allow a continuous infusion of pain relieving medications. Your epidural catheter is generally removed once you are able to keep down oral pain-relieving medications.

The femoral nerve provides sensation and motor function to the front of the thigh and knee. This block is commonly used for procedures that cover the knee. If you receive a femoral nerve block, you will be positioned on lying on your back. Your anesthesiologist will clean your groin area with an antiseptic (bacteria-killing) solution. If using an ultrasound, the anesthesiologist will place the ultrasound probe on your skin. An image of the femoral nerve will be obtained by scanning the area. Once the nerve is identified, the anesthesiologist will inject local anesthesia (“numbing medicine”) into the skin—this may cause a slight burning or pressure sensation. Your anesthesiologist will then carefully insert and advance a needle toward the femoral nerve. The ultrasound is used to visualize the needle as it approaches the nerve. The needle does not touch the nerve; it is stopped when it is near the nerve. Once the needle is in proper position relative to the nerve, local anesthetic is injected through the needle to numb the nerve. The local anesthetic can be seen surrounding the nerve with ultrasound. Sometimes a nerve stimulator is also used to help your anesthesiologist determine the appropriate location to inject the local anesthetic. If a nerve stimulator is used, you may feel the muscles in your leg twitch—this is normal. Your anesthesiologist may insert a small flexible catheter to allow for continuous injections or infusions of local anesthesia. The needle is removed and only the catheter remains at the end of the procedure if this is the case. As with other blocks, always let your anesthesiologist know if you experience any sharp or radiating pain during the procedure or injecting of the local anesthetic. You may have difficulty with weight bearing on the blocked leg, and you should have help in attempting to get up. Care should be taken to prevent falls.
